Preference option to disable EQ processing

[Kyle Dean]

I have a VMS4 which I has a hardware mixer built into it. I was wondering if in the future we could have a way to disable Mixxx's EQ and gain so I could just use the external mixer to take care of it . But it would be cool if the nobs still followed the controller and the waveform viewer still increased when turning it up.

You can disable the EQs on the VMS4. See the manual. You'll want to search for Post-EQ mode.

[RJ Skerry-Ryan (rryan)]

This would be very useful for people with slow CPUs -- the EQs are the hungriest part of Mixxx's engine. Plus people using external mixers will already be using their own EQs so this could prevent duplicated effort in the case that the user wants to use their external EQs.

[RJ Skerry-Ryan (rryan)]

The main problem with disabling parts of Mixxx's engine is that we don't have a good way to represent that a widget is disabled in the GUI. Adding this preference option is super easy .. probably about 20 lines of code total. Disabling the widgets is another story.

[Owen Williams (ywwg)]

In my own hack for this feature, I created a transparent pixmap that I overlay on the widgets to make them look disabled. In the default state, this overlay is just a transparent pixmap. This is a good solution visually, but unfortunately the widgets can't receive mouse clicks (because they have a pixmap on top). Maybe there's a way to do the same thing, but hide the disabling pixmap by default instead of showing a transparent pixmap when the disabling is... disabled.

[Owen Williams (ywwg)]

To be less confusing: when a feature isn't disabled, I use a completely transparent pixmap. When I have disabled something, I overlay a *partially* transparent pixmap that has diagonal lines.

Thats sounds cool Owen, I am particularly interested in how you achieved that transparent/ translucent pixmap overlaying? Sorry for being off the topic :) could you mail it on the list or something. Thanks.

Bug #1180872 will hopefully facilitate this.

I'm not sure about the gui component disabling... I would like to have them, working, so it can show the status of my controller... any other opinion ?

[RJ Skerry-Ryan (rryan)]

Will your controller send the hardware EQ knobs over MIDI? (e.g. they are tied to the hardware effect but still send their state over MIDI?)

My vision for the disabling in the GUI is that they would be shown as "greyed out" or dim, not hidden (or possibly in a collapsible section). The knobs would still turn in response to e.g. MIDI events but would not react to mouse input.

[Kyle Dean (kylemdean)]

Yes I belive that's how it works. It's been a while since I've messed with it. But it does use the potentiometer to filter sound sent through the mixer as well as send midi data.

Yes, seems to be :) It's an American Audio VMS4.1, and now if I don't
switch the EQs off, I get double EQs.... which makes huge overshoots...
(I'm recording from the output of the controller).
Disabling mouse, well I don't know if it's really necessary ? I mean the
ones using this feature will know why they do it... so they most probably
won't use the mouse to change those EQs... unless we disable it for saving
cpu...

@Peter -- you wouldn't have to do anything with the skins -- that's up to the skin designers whether to disable the widgets or not. The PR you just sent covers this bug completely.
